Add rounded corners to any Android interface with RoundR
There has to be a medal of some kind given to developers who come up with ideas as simple yet brilliant as this. Meet RoundR – an interface tweak developed by Mohammad Adib, who is apparently a fan of rounded corners. That's what his 68-kilobyte piece of software adds to the Android user interface – curves at all four corners with a radius that can be adjusted. Well, actually you can pick which corners get roundified, in case you want to. The UI modification is visible while browsing home screens, the app drawer, even when playing games. Apps that request full screen video playback, however, (think YouTube) override the modification.
RoundR for Android can be downloaded for free from the Google Play store so go ahead and give it a try. A download link has been provided for your convenience.
